vent persons being injured by flying particles' of the case when thetorpedo explodes.

This case is a divisional application of my application for railwaysignal torpedoes Serial No. 688,572, filed April 1, 1912.

My present invention consists in providing a cloth wrapping for asubstantially rectangular open-ended tubular explosive containin case;to close the open ends of the case by the cloth wrapping; to strengthenthe paper case of the cloth wrapping, and to. secure a metallicstrap-carrying clip to the case and the cloth wrapping carried thereby.

The object of my invention is to provide an efficient and cheapnon-metallic case torpedo, which will have its paper case strengthenedand the explosive within the case protected, the cloth wrapping -rnoreeffectually withstanding the wear in the handling of the torpedo thanthe exposed paper of the case. p

A further object of my invention is to so construct a cloth wrappednon-metallic torpedo by the use of special tools and appliances that itis adapted to have a metallic strap-carrying clip clamped thereto.

In the accompanying drawings: Figure 1 is a perspective view of myimproved torpedo showing it constructed with a metal strap-carrying clipand in position on a railway-rail. Fig. 2 is a sectional View on theline 2-2 of Fig. 1. Fig. 3 is a sectional view'on the line 83 of Fig. 1.Fig. 4; is a perspective view of the parts of the torpedo in separatedrelation showing the mannerof constructing the torpedo. Fig. 5 is anedge view of the torpedo and a section of the tools used for closing thecloth Wrapping tight when a metal strap-carrying clip is to be used.

Referring now to the drawings in which like reference characters denotethe same parts, 1 is a substantially r ctangular openended tubularcase-in which the xplosive compound 2 is placed. This explosive compoundis in the form of a tablet of a size to fit within the case 1. A paperplate 8 is constructed preferably of a size corresponding to theexternal size of the bottom of the case 1 to which it is applied. Apiece of cloth 7 is provided which is of a length sufficient to wrap thetop, bottom, and ends of the tubular explosive containing case 1. Thecloth is coated with suitable cement before it is applied and is thenpressed around the case. It is of a width corresponding to the length ofthe tubular case 1. The paper plate 3, above-referred to, extends beyondthe edge of the case 1 as shown at 3. Another piece of cloth 8 isprovided of a width corresponding to the width of the case 1 and of alength suflicient to pass twice around the .case and the projectingedges of the plate3 longitudinally. This piece of cloth is also coatedwith cement before it is applied and is wrapped around the case andafterward pressed down on the projecting ends or flanges 3 of the plate3, as shown in Fig. 5, by means of suitably shaped pressed dies 10 and11. To afford sufficient cloth to enable it to be pressed down along theedge of the case 1, as shown at 1, Figs. 3 and 5, a suitable prongedinstruent 12 has its ends 13 placed outside of the ends of the case 1,as shown in Fig. 1, to enable the cloth to be tightly wrapped around thetorpedo, and to provide sufficient cloth to enable it to be pressed downas shown in Fig. 5. This pressing, of course, is done before the cementon the cloth 8 has become hardened.

The construction of the metal clip 14: which receives a spring strap 17and the construction of the strap are. shown in a copending applicationand a specific interlocking construction of a strap and clip form nopart of my present invention and need not be described herein. The edges15 of the clip 14 are turned upward, as shown in Fig. 8, and thenthewrapped torpedo is placed between these bent edges and the edgesclipped down on the projecting edges of the torpedo as shown in Figs. 1and 3. 7

Having thus described my invention what I claim and desire to secure byLetters Patent is: I

1. A railway signal torpedo comprising a rectangular open-endedpaper-explosive containing case, a plate secured to the under sidethereof and having two edges projecting beyond the two edges of thecase, a strip of cloth wrapped and cemented around the case and theprojecting edges of the plate, the cloth presed against the projectingedges of the plate and the adjacent edges of the case, a second strip ofcloth wrapped around the case at right angles to the first said strip, ametal clip applied to the under side of the torpedo and clamped aroundthe cloth-wrapped projecting edges of the plate, and arail-engagingstrap attached to the torpedo.

2. A railway signal torpedo comprising an open-ended tubular explosivecontaining case, a plate secured to the underside thereof and having twoedges projecting beyond the two edges of the case, a strip of clothwrapped and cemented around the case and the projecting edges oi theplate, and a metal clip applied to the under side of the torpedo andclamped around the cloth-wrapped projecting edges of the plate, and arail-engag ing strap carried by the said clip.

3. A railway signal torpedo comprising a paper-explosive containingcase, a plate at the bottom of the said case and projecting beyond twoedges of the case, a strip of cloth wrapped and cemented around the caseand projecting edges of the plate, and a metal clip applied to the underside of the torpedo and clamped around the cloth wrapped projectingedges of the plate, and a rail-engaging strap carried by the said clip.

4. A railway signal torpedo comprising a paper explosive containingcase, a plate secured to the under side thereof and having two edgesprojecting beyond the edges of the case, wrappings of cloth around thecase and the projecting edges of the plate and a wrapping around thecase at right angles to the first said wrapping, and a metal clipapplied to the under side of the torpedo and clamped around the clothwrapped projecting edges of the plate, and a rail engaging strapattached to the torpedo.

5. A railway signal torpedo, comprising an open ended tubular explosivecontaining case, a plate secured to the under side thereof and havingtwo edges projecting beyond the two edges of the case, a strip of clothrapped and cemented around the case and the projecting edges of theplate, and a metal clip applied to the under side of torpedo and clampedaround the clothwrapped projecting edges ofthe plat and a arail-engag1ng strap attached to vthe torpedo.

In testimony whereof I hereunto atlix my signature in the presence oftwo witnesses.
